Tau/Z; whom it may concern:

Be it known that I, CYR B. WATTLES, a citizen of the .,United States,residing at Providence, in the county of Providence and State of RhodeIsland, have invented a new and useful Im rovement in Floor-DressingMachines, of w ich the following is a specification.

. raised floors of bowling-alleys, whereby the wise and crosswise of theraise dressing-roller is given simultaneously a rotary and a recirocating motion on the raised surface of the howling-alley.

My invention consists in the (peculiar and novel construction of afloorressing machine adapted to level, dress, finish, and polish theraised floors of bowling-alleys, said machine having a motor, adressing-roller covered with an abrasive or a polishing mate-- rial,mechanism operativel connecting the motor with the dressing-r0 ler tosimultaneously revolye' and reciprocate the dressingroller, meansfforadj ustlng the dressing-roller vertically, and means for supporting andguiding themotor and dressin' -roller lengthsurface of thebowling-alley, consistin of a carriage supporting the motor andressing-roller adapted to run on ways in a frame extending across thealley, which in turn is adapted to run on rails extending len thwise ofthe allgy to give an absolutely leve and true surface to the raisedfloor of the alley, with detail'sof con struction as will be more fullyset forth hereinafter;

Figure l is a plan view of my" improved floor-dressing. machine shown inits operative position over the raised floor of a bowlingalley. Fig. 2is an enlarged vertical view looking at the reci rocating-mechanism sideof the machine an showing the ways for the carriage and the raised floorof the bowlingalle in section. Fig. 3 is an enlarged vertica sectionalview taken on line X X of Fig.

2 through the carriage and raised fioor of the alley and showing themechanism for revolving and reciprocating the dressing-roller on theraised surface of the alley; and Fig. 4 is an enlarged detail sectionalview taken on line Y Y of Fig. 2 through thedressing-rollerreciprocating mechanism.

In the drawings, 0. indicates an "electric motor; I), thedressing-roller; c, the mechanism for revolving the dressing-roller; d,the

mechanism for reciprocating the dressingroller; 6, the carriagesupporting the motor, dressing-roller rotating and reciprocatingmechanism; f, a T-shaped handle pivotally secured to the carriage; g,the transverse frame forming the guideways for the carriage;

h h, the rails sup orting the transverse frame of Hi im rovefloor-dressing machine for bowling-a eys; and t,-the raised floor of abowling-alley.

The electric motor a derives its power from a, source of electric energythrough a flexible cable (not shown) and has the usual casing a3,constructed to form the base 0?, and the bearings a, a for the armatureshaft a, which extends through the motor. A sprocket-wheel a is securedto one end of the armature shaft g, and a grooved pulley a, secured tothe opposite end of the armatureshaft,'as shown in Fig. 3.

The dressing-roller bis secured to the shaft I), which is rotatably andreciprocally supported in the bearings c e, secured at each end to thedressing-roller b to the under side of'the carriage e, sufficient spacebeing allowed between the ends of the dressing-roller and the bearingsto allow for the reciprocav tion of the dressing-roller. A sprocket--wheel 6 is secured to-o'ne of e'ndthe shaft 1) and a grooved collar bsecured to the opposite end of the shaft, as shown in Figs. 3 and4.g' V

The'dressing-roller-revolving mechanism '0 consists of a sprocket-chainc, connecting-the sprocket-wheel a on the armature-shaft a with thesprocket-wheel b? .on the shaft b of the dressing-roller b, asshown inFig. 3.

The dressing-roller-reciprocatin mechanism (1 consists of a large oovedpu ley d and a small grooved pulley secured to a counter-shaft (irotatably supported in the bearings d d, which are secured to the top ofthe carriage e, as shown in Fi 2. A belt 6 connects. the pulley a on thearma'tureshaft ;of the" motor with the large pulley d. A

secured to the shaft (Z rotatably supported tr e tension of thewhip-spring d, which rebosses c e to which the flan ed wheels e e aregrooved pulley d, having the cam-face d", is

in the bearings d, which are secured to the to of the carriage e in aposition to bring the pidley d opposite the pulley (P. A belt aconnectsthe pulley d with the small pulley d on the shaft (i A vertical lever (ihaving the roll d rotatably secured in its upper end and the roll c2rotatably secured to its lower end, is pivotally secured near its centerto the lugs e e on the carriage e in a position for the upper roll d toenga e with the camface (1 on the pulley d and for the lower roll (1 toenga c with the grooved'collar b on the dressing-re ler shaft 5, asshown in .Fig. 4. A whi -s ring d is rigidly secured at one end to t ecaring d in a position for the free end ,of the spring toengage with theupper end of the leverdl as shown in Fig. 2. The camface (i on thepulley d operates to throw the 11 per end of the lever d outward againstturns the upper end of the lever to its original position. By thisconstruction the dressing-roller b is reciprocated in one direction bythe operation of the cam d through the lever d and in the oppositedirection by the ten sion of the spring (1 through the lever d.

The carriage c has the bearings e e for the dressing-roller shaft 1;,the lugs e e for the lever d, the raised central portion a to which thebase a of the motor is secured, the

rotatably secured, the bosses e e, to which the disks 6 e are rotatablysecured, the lugs e a to which the lower end. of the handle f ispivotally secured, and the outwardly-er;- tending arm e", in the end ofwhich is the vertical adjusting-screw "e as shown in Fig. 2.

The transverse frame g consists of the Y L- shaped cross-struts g g,forming rigid ways for the carriage e and secured together at the ends apredetermined'distance apart by the rods 9 g. 011 the sides near theends of the cross-struts g g are the outwardly-extending lugs g y towhich the flanged wheels 9 g are rotatably secured.

The L-shaped rails h It are secured to the floor at each side of andparallel with the raised floor i, of the bowling-alley andsup- 7 portthe transverse frame 9 through the flanged wheels g g" on the frameengaging with the rails. The carriage e is supported on thecross-strutsv g g of the transverse frame 9 by the flanged wheels g gei'i'gaging with the bottom and inner edge of oneof the crosastruts g,the disks 6 e engaging with the inner edge of the opposite cross-strut gand the lower end of the adjusting-screw 0 engaging with the bottom ofthe adjacpnt cress-strut, as shown in Fi 2. By adjusting the set-screwe, the dressing-roller b is give' a vertical adjustment to vary thepressure of the dressing-roller on the raised floor of thebowling-alley.

in the operation of my improved floordressing machine for bowling-alleysthe first leveling or rough cut is usually made by a roller com osed ofa plurality of circular saws. R0 lers covered with'coarse, medium, andfine sandpaper are now used in succession for dressing and finishing andfor olishing a roller covered with felt or cloth aving a loop pile ornap may be used. The dressing-roller b is revolved at a high rate ofspeed on the surface of the raised floor t of the alley by the motor athrough a sprocket-wheel a the chain c, and the sprocket-wheel b on thedressing-roller shaft 1), and simultaneously the dressing-roller b isreciprocated throu' h the pulley a, the belt (i the pulley d, t e pulley(1 the belt d", the pulley d", the cam d the lever 11, and the groovedcollar b on the dressing-roller shaft 12. The operator now moves thecarriage e and the transverse frame 9 on the rails h h by the handle flengthwise of the raised floor '5 of the alley. At each lengthwisemovement of the carriage and frame the carriage e moved in the frame 9crosswise of the alley a distance approximately the length of thedressingro ller.

It is evident that any form of a motor may be used and that theconstruction of the machine may be varied so that the dressingroller maybe operated crosswise of the raised floor of the bowling-alley withoutmaterially aiiecting the spirit of my invention.

Having thus described my invention, I claim as new and desire to secureby Letters Patent l. in a floor-dressing machine, a carriage, means forsupporting and guiding the carriage lengthwise and crosswise over theraised floorof a howling-alley, a motor secured to the carriage, adressing-roller rotatably and re ciprocally secured to the carriage,mechanism operativel the dressing-roller'whereby the dressing-roller isgiven simultaneously a rotating and a reciprocating motion, and meansfor adjusting the dressin -roller vertically, as described.
